I was a guest this week on the Network Security Podcast, speaking with Rich Mogull, a frequent TidBITS contributor. We spoke about the early concerns with the security model and certain parts of the way it works in Leopard. Specifically, we focused on stuff that's hidden from most users (library randomization, application signing, and sandboxing); the new firewall and how it really, truly sucks; and concerns about Back to My Mac, a great feature that raises a lot of questions about risks of exposure.

We talked for an hour, and in some cases barely scratched the surface. Rich has a list of further reading at his site.
